After a scintillating first quarter of his rookie season, Washington Redskins quarterback Robert Griffin III's ascent to an every-week fantasy start is complete.

With a system catered around his strengths and continual top-notch performances, it is no longer a question of whether to start RGIII, but of just how many points he'll get you on Sunday.

That will certainly be the case in Week 5 when the Redskins take on an undefeated Atlanta Falcons team. Led by ferocious attacks on both sides of the ball, the Falcons will present a unique challenge to the upstart Washington squad.

What does that mean for Griffin's value? Here is a look at our projections for the breakout star's performance against Atlanta on Sunday.

Passing

While Griffin has thrown just one interception in 124 pass attempts this season and has displayed fantastic decision-making skills, he'll get his toughest test thus far on Sunday.

The ball-hawking Falcons secondary comes into Week 5 having already intercepted Philip Rivers and Peyton Manning a combined five times while allowing just 207 passing yards per game, good for eighth in the NFL.

That means we're likely to see Griffin add to his interception total at least once on Sunday. Veteran cornerbacks Asante Samuel and Dunta Robinson should be able to blanket the Redskins on the outside, leaving the throwing windows much smaller than usual.

Griffin's trend of getting hit hard in the pocket will ostensibly continue as well with players like John Abraham coming off the edge.

If you were expecting the Redskins' signal-caller to win your contest through the air, that won't happen in Week 5. Don't expect him to look like a lost puppy out there, but a middling performance with a touchdown and at least one interception seems reasonable.

Luckily for fantasy owners, Griffin brings a whole different skill-set to the table that should allow him to thrive in other facets of the game.

Rushing

Running the ball is where Griffin's fantasy value has soared all season, and that should be the case once again against the Falcons.

Though Atlanta's pass defense is top-notch, the unit has struggled mightily against the run, giving up 146.3 yards per game (28th in the NFL) this season.

Those deficiencies should open up the possibility of a huge ground performance from Griffin on Sunday. The Redskins dual-threat leads all quarterbacks with his 234 yards and four touchdowns gained on the ground.

Facing off against a vaunted Atlanta aerial attack, the Redskins will look to control the clock by relying heavily on the run. To keep the rushing attack fresh, expect head coach Mike Shanahan to call a stretch of read options with Griffin and running back Alfred Morris.

While his upcoming passing struggles may cause you to fret, Griffin should make that up in spades by excelling with his legs.

Overall

Even in his absolute worst throwing day, Griffin will have Top 10 fantasy value based on his running ability alone.

He's obviously in your starting lineup in just about every format. I just wouldn't expect him to single-handedly win any matchups in Week 5.
